Getting to see all that Cape Town has to offer with Justin was just incredible. He took me and some of the band out to go snorkeling with seals - definitely a highlight! Not to mention a visit to the turtle aquarium and a kayak trip in Table bay. Unforgettable experiences!

RockHopper is the brilliant invention of Justin Blake, who has entranced a multitude of tourists with his joyous knowledge about the riches of our coastline, and whose ‘Just On Marine’ newsletter is a fount of information.

Such a wonderful and memorable marine tour. Everything was exceptionally professional and perfectly planned, even beyond my expectations. I really couldn't have asked for more from my ocean experience and I cannot recommend RockHopper more highly from start to finish.

Scientists First, Storytellers Always
We’re not a tour company that adds conservation later — we’re marine biologists who began in the field, studying sharks, kelp forests, and coastal ecosystems across Southern Africa.
Our work spans from tagging sharks to creating virtual dives for rangers who protect the ocean but rarely see beneath the surface.
RockHopper was born to share that world with you — transforming scientific understanding into private, life-changing journeys that reconnect people with the ocean.
Let’s design your ocean experience together.
Not Just a Tour.
A Scientist’s Ocean, Shared With You.
Most tours show you the surface. We take you deeper. Our safaris are crafted by conservation biologists who spend their lives decoding the ocean. We’ve worked on Planet Earth 3, Netflix Oceans and more.
With us, you gain rare access: insider knowledge, intimate encounters, and authentic stories.
Every moment is private, bespoke, and unforgettable.
Each guest experience directly supports marine conservation efforts: shark tagging, youth education, and globally actionable marine research.
